When we take our dog to the beach she takes off and we can't catch her. Should we use a shock collar?

Hi,

I have just recently discovered your training techniques for my 7 month old husky female. We got a prong collar on her a couple months ago, as per suggestion of our trainer to correct her pulling, but made a huge mistake in not correcting when she would not come when called. We thought that if she didn't listen, but then eventually came to us, we should not correct her because she is after all coming to us. Writing it now, I know that was the WRONG choice.

So now we have a pup that we cannot trust to come back to us when we call, which we know is our fault. When we go to the dog park or the dog beach, she takes off and usually takes about 10 minutes to catch. We have the long line on her now and are practicing the techniques from your videos-paying particular attention to "come." Do you recommend getting a shock collar since she has been able to ignore us so many times? Or do you think we can fix this with the prong collar training steps you use? Thanks.

I appreciate the advise. It certainly makes sense. Thank you!!
